Left vocal cord paralysis  (Abductor Muscle - Raspy Voice) This video shows the function of a larynx from a 35 year old white female with a left true vocal cord paralysis.  The paralysis occurred after the removal of a mediastinal mass involving the aortic arch.  Note that the cord is lateral (away from the midline of the larynx ) and bowed.  The voice is hoarse but only mild weakness is present since the patient has partially compensated.
